Section 19:6-2.39 - General requirements for installation of piles

(a) Piles shall be installed with adequate provision for the protection of adjacent buildings and property.

(b) Piling shall be handled and installed to the required penetration and resistance by methods that leave their strength unimpaired and that develop and retain the required load bearing resistance. Any damaged pile shall be satisfactorily repaired or the pile shall be rejected. Subject to the approval of the chief engineer, damaged piles may be used at a fraction of the design load as determined by the architect or engineer in lieu of repair or rejection.

(c) Where boring records or site conditions indicate possible deleterious action on pile materials due to soil constituents, changing water levels, or other causes, such materials shall be adequately protected by preservatives or encasements that will not be rendered ineffective by driving and that will prevent deleterious action. The following specific provisions shall apply:

1. Untreated timber piles shall not be used unless the top level of the pile is below the permanent water table. The permanent water table level shall not be assumed higher than the invert level of any sewer, drain, or subsurface structure in the adjacent streets, nor higher than the water level at the site resulting from the lowest drawdown of wells or sumps, but in no case shall untreated timber piles be used where the cutoff level is less than ten feet below the adjacent legal grade. Where treated piles are required, preservation treatment shall consist of impregnation with creosote solution, or for piles entirely embedded below grade, a pentachlorophenal solution may be used. Treatment shall be in accordance with all requirements of this subchapter.

2. Piles installed in ash or garbage fills, cinder fills, or which are free-standing in or near a sea-water environment, shall be investigated regarding the need for special protective treatment and, where protection treatment is indicated, shall be protected against deterioration by encasement, coating, or other device acceptable to the chief engineer.

3. Equipment: Equipment and methods for installing piles shall be such that piles are installed in their proper position and alignment, without damage. Equipment shall be maintained in good repair.
